Question

calcule o valor de X nos triângulos retângulos​

Answer 1

a) h²=m.n

x²=9.16

x=√144

x=12

b) b²= a.m

3²=5.x

9=5.x

x=9/5

x= 1,5

c) c²=a.n

4²=5.x

16=5.x

x=16/5

x= 3,2

d) a.h=b.c

25.12=b.20

300=b.20

b=300/20

b=15

e) h²=m.n

8²=4.x

64=4.x

x=64/4

x=16

f) c²=a.n

20²=x.16

400=x.16

x=400/16

x=25
